... that the major factor which determines the rate at which flying-fox populations increase or decline is mortality, and that an additional annual mortality of 10%, “imposed” (for example by “culling”) upon the animals' “natural” mortality, could lead the entire Grey-headed Flying-fox population into decline...

... Exclusion netting systems are the only humane method for preventing flying-fox damage to orchards, especially during seasons when natural food is in short supply. As the forests that provide natural food are eliminated, and flying-fox pressure on orchards therefore increases, the need...

... to an increase in the intensity of logging. An outcome will be the cumulative loss of stand structural complexity—a problem that has had serious consequences for the conservation of biodiversity in northern hemisphere forests and would have similar deleterious impacts in Australia. It also runs counter...

... This is a discussion of the ways in which postage stamps might serve to raise awareness and interest, and through associated media and events, to increase understanding. ...

... on the distribution of species. A number of large marsupial herbivores occur at lower subalpine elevations, and a shift in their distribution to higher altitudes due to climate change will result in increased grazing of the vegetation of the alpine area. Common wombats Vombatus ursinus were chosen as a model...

... was highly sensitive to increases in adult mortality. Under the basic model, with a 30% chance of fox arrival each year and the carrying capacity of the headland at 120 bandicoots, the population had a 10% chance of going extinct within 20 years due to chance events. When adult mortality was increased to 11...

... The town of Anglesea on the west coast of Victoria is famous for its Eastern Grey Kangaroos. However, conflicts have increased between people and kangaroos in the town. Many concerns are centred on the golf course, which can support a population of over 300 kangaroos at times. Roadkills...

.... Instead, passerine species richness declined with increasing Distance to Bushland and with increasing Housing Density, but increased proportionately with the Size of, Nearest Bushland > 5ha. Together, these predictors explained approximately half the variability in bird species richness (adjusted R 2...

... of increasing numbers of Australians, increase the coverage and density of invertebrate data collections and assist invertebrate conservation and management. ...

... in a marked improvement in the condition of our local vegetation, leading to tangible increases in habitat potential. Recent fauna surveys, including professional systematic and community opportunistic reports, have indicated both an increase in the population and diversity of local indigenous fauna. ...

... We reviewed published, quantitative studies examining the effects of exotic plants in native vegetation on the species richness and abundance of birds and mammals. We asked whether the incursion of exotic plants into native vegetation has led to consistent declines, increases or no changes...

... increases in abundance and size of exploited species such as Snapper Pagrus auratus , Spiny Lobster Jasus edwardsii and Blue Cod Parapercis colias in marine reserves. Significant increases have been rapid, occurring within one year in the case of snapper, but only evident where full no-take protection...

... Pests are species that, when they become overabundant, have unacceptable effects on humans. Ironically, humans themselves have greatly increased their abundance in the last century. Although this increase, together with concomitant scientific and economic growth, has brought many benefits...

... metapopulation), had an unacceptably high probability of glider extinction after 100 years. When catastrophes such as wildlfire of modest frequency (1 in 20 years) were included, the probability of extinction increased. It appears that large nearby remnants must be functionally linked to the metapopulation...

... husbandry to suit Australian environments. Livestock enterprises affected by predation should be encouraged to: • Reduce local attractants, such as unspayed domestic dogs; and • Increase use of deterrents, such as guard animals. Culling by appropriate authorities of troublesome individual dingoes...
